Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

open access: yesThe Anatomical Record, Volume 308, Issue 12, Page 3069-3081, December 2025.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.
